The bulk of research within the interactionist framework seems to be consensually pointing to the beneficial effects of interaction in SLA. However, few studies have investigated the role of training in providing and perceiving interactional feedback, especially among young learners. This study probed the effects of training prior to engagement in interaction in case of young learners acquiring...

We consider an experimental system consisting of a pendulum, which is free to rotate 360 degrees, attached to a cart. The cart can move in one dimension. We describe a model for this system and use it to design a feedback control law that stabilizes the pendulum in the upright position. We then introduce a time delay into the feedback and prove that for values of the delay below a critical dela...

Abstract The study aimed at investigating the efficacy of written corrective feedback (CF) in improving Iranian EFL learners’ grammatical accuracy. It compared the effects of focused and unfocused written CF on the learners’ grammatical accuracy. 75 EFL students formed a one control and two experimental groups. The focused feedback group was provided with error correction in tenses. The unfocus...

A Robust Anti-Windup Control (RAWC) method is proposed for n-Degree-of-Freedom (DOF) electrically driven robots considering the actuator voltage saturation. The actuator’s saturation is fairly modeled by a smooth nonlinear function and the control design task is developed to avoid windup besides being robust against both model uncertainties and external disturbances. As a major point, the paper...

The purpose of this study was to explore the role of two multi-step oral-revision processes as feedback providing tools on Iranian EFL learners’ argumentative writing achievement. The participants taking part in this study were 45 Iranian EFL students who were randomly assigned into three groups. The participants of the groups were given three argumentative writing assignments, each assignment ...

A new approach for pole placement of nonlinear systems using state feedback and fuzzy system is proposed. We use a new online fuzzy training method to identify and to obtain a fuzzy model for the unknown nonlinear system using only the system input and output. Then, we linearized this identified model at each sampling time to have an approximate linear time varying system. In order to stabilize...

Controversy has not been yet resolved among researchers in second language research over the pedagogical efficacy of feedback in enhancing various features of learners’ writing skill. Research findings highlighting the significance of interactive tasks and learners’ engagement in improving the learning process stimulated the present study, the purpose of which was to explore the effect of task-...
